3 Claims. (cuss-.12).

This; inventionrelates improvements in. air conditioningunits;

The primaryobject of the invention isto provide an air conditioning;unit that will eithercool or heat the-surrounding-area.

further object; of: the invention is. to wash, cleanse and; sterilizethet-airr taken into the unit and: delii'er'fresh; airtherefrom eitherheated or coo 'o tort its:eXi i a cmp ure;.

A still further object of the invention is the provision; ofmeansionhumidifying the air being delivered through the machine.

And a further object of thev invention is to provide automatic controlsfor controlling the operation ofzthe unit;

These and other incidental objects will be apparent in the drawingsspecifications and claims.

Referring to the drawings:

In the drawings:

My new and improved air conditioning unit consists of a cabinet Idivided by a vertical partition Ia to form two compartments 5 and 5a.The lower end of the partition terminates above and spaced from thebottom of the cabinet to provide a passage 5b between the twocompartments 5 and 5a. A conventional type blower fan 2 is mounted incompartment 5a underneath the top 3 of the cabinet. A suitable drivingmotor 4 is mounted within the compartment 5 of the cabinet and. drives:the; fan; 2 through the; belt 63- from the pulley 1 to the driven;pulley.- 8:. keyedto the countershaft: 9...

The; mechanism forwhich Ido-nota t mnt: o Show The; cooling; coils [8; are; connected to.the refrigeration unit, I9 throughsuitable, pipe 20. The water;- I.aintai ed. ata. low temp ature by the; refrigeration coils and; isdelivered fromv the tank; l2- throughthe-piping 2|, pump 22, piping23zoutthrough thespray nozzles-2.4 and directed downwardly; through thescreens. 25 and back downinto the pan 12 for recirculation. The screens,are for the purposepf. breaking up the water assisting in. the. cooling,washing and cleansing effect.

The operation of; the blower or fan 2. draws air throughthe, adjustablegrill '26 and up. through the screens,ZSandthrough thefilter. unit 2'!into the fan at 28 and discharging the same, through the fan nozzle 29,thence through the grill into the surrounding area, as for instance aroom to be cooled. The pump 22 is driven from the motor 4 through thebelt 3|. The operation of the motor 4 is controlled by a suitablethermostatic control 32, which I show diagrammatically in connectionwith Figure 1 for clearance of operation, although this is not the waythe wiring would appear. A control switch 33 may be operated by hand orautomatically by the thermostatic control 32 stopping or starting themotor.

I have just described the air conditioning operation as having been usedfor cooling, cleansing and sterilizing and humidifying. When it isdesired to use the same as a heating unit together with air cleansingand. humidity control, the screens 25 are removed and the radiator unit34 is installed in their place. The radiator 34 receives circulatingwater or steam through the piping 35 from the hot water or steam tank36, the detail of which I have not attempted to go into mechanically, asany suitable source of supply may be used in connection with my airconditioning unit. When the heating radiator 34 is used the pump 22 maycontinue to supply Water over the surface of the heating unit asrequired to add humidity to the air, but excellent results are obtainedwhere the belt 3| is removed from the motor and the pump and the aircoming in through the air intake grill 26 passes over the surface of thewater l3 within the tank 12 causing the same to evaporate up through theheating radiator 3|, which heats the air which then is delivered throughthe filter 21 and the fan unit 2 as above described.

One of the outstanding features of my invention is the including of asterilizing unit 31; in the path of the air. This sterilizer unit mayhave a medicinal material contained 'therein, andit may be located atany desired'location within the air conditioning cabinet but in the pathof the air that is being conditioned and discharged,

Many combinations may be added by the inter changing of the variousparts within my air con ditioner, but the combination I have justdescribed provides' the necessary-features to fulfill the objects of 'myinvention; 1 r I do not wish to be limited to the exact mechanicalstructure shown and described, as other mechanical equivalents may besubstituted still coming within the scope of my claims.

What I claim as new is: a r
